How to get creation timestamp of input file

Am using logstash to parse an input logfile and subsequently sends data to elasticsearch. I would like to capture the creation date/timestamp of the input logfile as a field on the event. How best to go about this? Fyi, i've very new to using logstash. Thnx

As far as I know that is not possible.

In general, you have OOB filter plugins, if they support your requirements like data parsing(for instance grok or csv) you can in it used it. For any other things, there is ruby plugin which opens a new world of endless possibilities.
So, Christian is correct, it's not possible by default-there is no plugin or property, but with ruby it's not so complex.
